Facebook workers turn on Zuckerberg: Founder and CEO could be forced out amid fallout from company of spying on users' calls and signing secret deals to hand over their data, insiders reveal

'Facebook employees are turning on boss Mark Zuckerberg, it was reported last night as British MPs accused the company of spying on users' calls and texts and signing secret deals to hand over their data.

Former workers have described a 'toxic and hostile' atmosphere at the social media juggernaut which has suffered a torrid few years battling data scandals and fake news.

One former senior employee told Buzzfeed News that workers are desperate for a change of leadership.

'People are hoping for a Sundar or Dara moment,' the worker said referring to Uber's new boss Dara Khosrowshahi and Google's chief Sundar Pichai.

Another said staff fear being scolded by furious bosses who are 'spouting full-blown anti-media rhetoric, saying that the press is ganging up on Facebook.'

The source revealed: 'People now have burner phones to talk shit about the company - not even to reporters, just to other employees.'

They said staff are at rock bottom, adding: 'It's the bunker mentality. These people have been under siege for 600 days now. They're getting tired, getting cranky - the only survival strategy is to quit or fully buy in.'
